Abstract Light‐driven greenhouse gases upgrading (GGU) into syngas is a promising approach to reduce CO 2 emissions and supply green fuels simultaneously. However, this reaction usually suffers from high operation temperature low conversion rate due stringent thermodynamic constraints. Herein, selective plasmonic CH bond editing strategy presented via incorporating ultralow amounts of Cu Ni‐based catalysts by electrostatic adsorption. A remarkable 2.69 times as the limit extraordinary light‐to‐fuel efficiency 24.95% at 500 °C are achieved, outperforming state‐of‐the‐art literature reports.

Simultaneously, intermediates proceed along CH+ O = CHO rather than C+ H, thus avoid complete subsequent coke deposition, leading stable on‐stream over 20 h.

Achieving on-chip, full-UV-band photodetection across UV-A (315-400 nm), UV-B (280-315 and UV-C (100-280 nm) bands remains challenging due to the limitations in traditional materials, which often have narrow detection ranges require high operating voltages. In this study, we introduce a self-driven, on-chip photodetector based on heterostructure of hybrid gold nanoislands (Au NIs) embedded H-glass cesium bismuth iodide (Cs3Bi2I9). The Au NIs act as catalytic nucleation sites, enhancing crystallinity facilitating vertical alignment interconnected Cs3Bi2I9 petal-like thin film. A built-in electric field developed at heterojunction efficiently separates hot holes generated under UV illumination, transferring them valence band minimizing recombination losses. device demonstrates an ultrahigh open-circuit voltage 0.6 V, exceptional responsivity 0.88 A/W, threshold 90 nW/cm2, outperforming existing film-based photodetectors self-driven mode. Long-term stability tests confirmed robust operational reliability ambient conditions for up eight months. This architecture, driven by efficient hole dynamics, represents significant advancement optoelectronics with promising applications environmental monitoring, flame detection, biomedical diagnostics, secure communication systems.
